MD-97 Brookeville Bypass Construction Management at Risk (CMAR) Project Overview
MD-97 Brookeville Bypass Project aims to address roadway deficiencies and increasing traffic volumes while preserving the historical character of the town. The construction will involve building a two-lane roadway, roundabouts, bridges, stormwater management, and other elements to enhance traffic operations and safety conditions.

MD 97 Brookeville Bypass Construction Management at Risk (CMAR) Project Presented By: Sean Campion P.E. Assistant Division Chief, Innovative Contracting Division
Overview MD 97 Brookeville Bypass Overview Construction Management at Risk Project Delivery Overview Overview of the Procurement Process
Background MD 97 is an arterial highway serving the east Montgomery County corridor and central Maryland from Washington, D.C. and the Capital Beltway (I- 495) to I-70 in Howard County. MD 97 functions as a major north-south commuter route between the employment areas in and surrounding Washington, D.C., and the residential communities north of Brookeville, including northern Montgomery County, Howard, and Frederick Counties.
Need for improvement Roadway deficiencies dog-leg or S curve located along MD 97 (High Street, Market Street, and Georgia Avenue) Increasing traffic volumes ADT: 2013(10,400) 2033(12,700) Truck: 5% Need to preserve the historical character of the town Brookeville is recognized as a historic district and was listed on the National Register of Historic Places in 1979.
MD 97 Brookeville Bypass Purpose and Need To remove the continually increasing traffic volumes from the Town of Brookeville, improve traffic operations and safety conditions on existing MD 97, and preserve the historic character of the town. Project Objectives Construct a two-lane roadway to move the traffic from the town. Minimize environmental impacts (stream, wetland, forest, parkland, archeological features etc.). Preserve the historic character of the town.
Project Elements: Construction is anticipated to consist of the following major elements: Construction of 0.72 mile long roadway pavement Two roundabouts at the southern and northern termini Two bridges crossing Reddy Branch stream and Meadow Branch stream SWM and ESC Retaining walls Removal of a bridge Replacement of the culvert at Brookeville Road Traffic barrier Landscaping Signing and pavement marking Stream relocation, wetland mitigation, forest mitigation.
Project Challenges: Watercourse 1 (Reddy Branch) and Watercourse 2 (Meadow Branch) are Class IV-P waters (Recreational Trout Waters and Public Water Supply). Structures are proposed to cross these two streams. Intermittent Watercourse 3 and Perennial Watercourse 4 are tributaries to Meadow Branch. Watercourse 3 is expected be impacted and would require mitigation. Impacts to Watercourse 4 needs to be avoided. In-stream work is not permitted from March 1 through May 31. The alignment goes through M-NCPPC parkland and ESD facilities for SWM were not considered in original study. Avoidance and minimization of additional of increased impacts to parkland and forest is desired. Archeological sites are expected to be impacted and the impacts should be minimized. Avoidance and minimization of temporary impacts to natural resources during construction is desired.

Construction Management at Risk (CMAR) Project Delivery
What is CMAR? A project delivery method where SHA utilizes a two-phase construction contract with a General Contractor to: 1) Provide Preconstruction Services which may include, but are not limited to, constructability analysis, value analysis, scheduling, site assessments, and cost estimating; 2) Construct the project based on final design plans (or design packages) at an agreed Guaranteed Maximum Price (GMP)
Authority State Code of Maryland Regulations (COMAR) 21.05.10 Federal Moving Ahead for Progress in the 21stCentury (MAP-21) Construction Manager/General Contractor (CM/GC)
Project Delivery Methods Design-Bid-Build CMAR Design-Build
Project Development Design-Bid-Build (DBB) Preliminary Design Detailed/Final Design Bid Construction CMAR Preliminary Design Detailed/Final Design CMAR Construction Procurement Design-Build (DB) Design-Build Procurement Detailed/Final Design Preliminary Design Construction
Reasons for choosing CMAR Shorten Project Delivery Project Complexity Contractor Input During Design High Number of Potential Risks/Risk Allocation Scope Flexibility/Maximizing Dollars Cost Analysis of Multiple Design Options Informed Owner Decision Making
CMAR Risk Allocation Contractor Owner DBB DB CMAR 18
CMAR Expectations Meet Project Goals Fair Market Price At or Below Proposed Price Improved Schedule Fewer Change Orders
CMAR Benefits Opportunity to bring on contractor during the design phase to work as an integrated team with the owner and its consultant/engineer to deliver the most efficient, and cost effective design Promotes innovation & collaboration Owner maintains decision making authority Greater cost certainty through GMP and reduction in change orders Still allows phased construction similar to design-build resulting in accelerated completion times. Phases must be severable. Risk identification & management during design phase and controlled by the team Owner gets up front benefit of value engineering CMAR design documents are biddable packages, not necessarily full set of biddable contract documents
CMAR Potential Risks Transparency Technical Qualifications and Approach are Main Elements for Selection Cost Validation Negotiated vs. Bid Culture New Process for All (SHA, Consultants, Contractor, Regulatory Agencies, Etc.) Risk Limited Historical Usage for Heavy Highway Construction
Procurement of General Contractor Best Value Selection One Step Process Technical Ratings - Adjectival Method of Selection Best Value Technical Proposal Qualifications/Past Performance & Project Approach Price Proposal Preconstruction Fee/Other Elements Technical Proposal is significantly more important than Price
CMAR Project Team Owner (SHA) Engineer under separate Contract with owner to provide all design services for the project. Two Phase Contract with General Contractor (GC) Phase 1 Preconstruction Services - GC considered part of the design team providing constructability, cost, schedule and risk management input. Phase 2 GC and Owner agree on GMP to construct the project based upon final design plans (or design packages). If GMP cannot be agreed upon, then advertise as design-bid-build.
Independent Cost Estimator Independent party hired by SHA to prepare a series of detailed estimates. Estimates are performed independently from Contractor and SHA s Designer. Estimates are utilized as a basis of comparison for review of Contractor s GMPs and award of Construction Contract.
Cost Model Development Develop Cost Model for Project Opinion of Probable Construction Cost (OPCC) Guaranteed Maximum Price (GMP) Elements of Cost Model Profit and Indirect Overhead Percentage Equipment Types and Rates Material Sources Subcontractor Items of Work Risk Agreement and Assignment Schedule
Cost Model Development OPCC To be submitted at various Design Completion milestones Blind Estimate Comparison Report of Items Outside of Tolerance (>10%) Reconciliation Meeting to discuss differences in bidding assumptions
Once Design is Complete Contract documents have been developed collaboratively by team Follow typical procedures DBE goals established for construction 2008 Standard Specifications and current SP/SPIs GMP - Contractor and ICE will independently price project
Once GMP is Submitted Contractor and ICE prices Price Reconciliation Meetings as needed Up to 3 GMP Submittals allowed Accept GMP and Award Contract Terminate Contract and Bid Project as DBB
